    Yes and No...

    I have cleaned/opened up ID acme threads using the OD threads of an acme screw.

    I used a bridgeport, and cut slots down the Acme screw (about 2-3 inches). This acts like a tap...

    I don't recommend doing it this way cause your major and minor of your thread will be incorrect, your delrin acme nut will be tight on the screw... but I guess it works in a pinch...

    (Acme threads are pretty easy, I do them almost every day) :-)

    It's a bit trickier, due to the higher lead, but it should work OK.
